Purge Reservoir
Bendix

Purging a heavy-duty air-brake system requires a dedicated reservoir to release condensate and moisture before it enters downstream lines, helping maintain clean, dry air for brake actuators and maintaining system reliability. While the feature set for this unit is minimal, its role in purge cycles improves overall longevity, reduces corrosion risk in moisture-prone lines, and minimizes water ingress that can cause freezing or erratic brake timing in cold climates. Designed for compatibility with standard Bendix purge and desiccant configurations, the reservoir’s compact form factor supports straightforward installation within chassis rails or under-hood mounting points. VMRS 013-010-495 categorizes it among purge and moisture-control devices; cross references are not listed, but its use is common in fleets seeking to maintain air quality and reduce maintenance downtime. Technicians should verify proper connection to supply lines and seals to ensure consistent purge flow and avoid false air signals that can affect braking response in highway applications. Category 41449 places it within the air and compressor subsystem, highlighting its practical impact on system reliability.
